TWISTED-NET FABRIC.

Lll i'n ddo Application filed November 18, 1914.

To all whom it may concern."

Bejit known that l, FRANK Cranmer, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Twisted- Net Fabric, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is proiide a new and improved open work lmitted fabric especially adapted for use in the man ufacture of laundry bags and dytrs bags. Such bags are subjected to hard wear and are sometimes cut or torn at diflerent points. It is important, therefore, that they should. be so knitted that if so torn or cut the damage will be localized This necessitates the knitting of the fabric in such manner that the threads of which the fabric is lmitted shall he interlocked at very frequent intervals in the knitting operation so that it will be absolutely impossible to ravel any particular thread or chain beyond a very small distance The fahric may he knitted. on a sauce a. the fabric is lniitted. Any given chain,

however, is termed partly of the threads of one pair and partly of the threads of another pair; this being edected by causing the threads of a given pair, after they have been interlooped to form a series of loops of one chain, to he diverted laterally and then interlooped to form a series oi iocps of a other chain, after which thcyare diverted laterally in the opposite direction, and then. interlooped. to form another series of loops of the first chain, and so on. L-etween the first and last named series oi loops of the first chain is an intermediate series of loops formed another pair of threads the junction between two series of loops of the same chain, one of the threads or the pair torn: "or; one of said two series of iocps is loo around one of the threads of the pair forming the other or two series of Specification of Letters Patent.

%oops, thus tying together the two series of oops.

in the preferred form of my invention, one thread of each pair, which I call the locking thread, always performs the looping function, while the other thread of the pair, which 1 call the locked thread, is the thread which is confined by the loop of the locking thread of another pair; the loclred thread at this point being itself formed into a loop through which extends the locking thread of the last named pair in its transverse extension toward the ad'acent chain. Thereby the threads are inter ocked at this point in such manner that accidental raveling is impossible in the event of breakage of any of the threads adjacent thereto.

The construction will he better understood by reference to the accompanying drawings showing a preferred form of my invention, in which Figure 1 is an enlarged face view of the fabric in which, however, the fabric is distorted to show the lonwitudinal rows of loops extending in a straight line and to accentuate the open-work eti'ect. Fig. 2 is a face view showing more accurately the appearance of the fabric to the eye a y, z, represent three adjacent longitudinally extending chains.

a, I), represent respectivel the locking thread and locked thread 0 one pair of threads. of, 5, represent respectively the locking thread and locked thread of another pair ,of threads.

It will he understood that the terms locking and locked are employed somewhat arbitrarily, the fact being that the connection between these two threads is more in the nature of an interlocking connection.

It will he observed that threads a and b are interlooped to form a series of loops in the chain 03, thence extend transversely and form a series of loops in the chain 2;, and thence extend transversely to form another series of loops in the chain a2; and so on, Threads a and Z) are interlooped totorin a series of loops in the chain y, thence extend transversely and form a series of loops in the chain a, and thence extend transversely and form another series of loops in the chain y, and so on. Thus, the chain 3,: is formed of a number of series of loops todraw out and elongate in a lateral direcformed by threads at and b alternating with a number of series of loops formed by threads 61 and b. The other chains are similarly formed partly of loops formed by one pair of threads and partly of loops formed by another pair of threads.

It will be, observed, by reference to (say) the lower part of the section of chain 3 shown in the drawings, that thread a is formed into a loop which extends around thread b at two points in its length or more specifically, thread a is formed into a loop .1 which extends around the neck of a loop 2 formed by thread I). The loop 2 formed by thread 5 is interlooped with a loop 3 formed by thread a, which latter thread also ex- :tendsthrough loop 2 formed by thread I) and thence extends together with thread 1)) transversely toward the chain :11. The said loop 8 formed by thread 1; extends around the neck of a loop 4 formed by thread I), which loop 4 in turn extends around the neck of a fifth loop'5 formed by thread a; threads 11 and b thence extending transversely toward the chain 0:. The said fifth loop formed by thread a corresponds to said first loop formed by thread a, and engages thread I) in the same manner as thread a. is above described as engaging thread I). It will thus be understood that I have described a complete single repeat of the fabric along the line of a single chain, including its connection with adjacentrepeats, which will sufiice for an understanding of the entire fabric.

' After the fabric is knitted the fabric tends to assume the form shown in Fig. 2; that 1s, the tying-in loops of threads a, 0, etc., tend tion owing to the pull between each series of loops in one 'chainand the two series of loops formedby, the same pair of threads in an adjacent chain. This produces irregular but's milarly shaped rows of figures, the figures of each rowbeinfg alternately staggered to the right and le Itwill be observed also that the threads are twisted one upon another, thereby producing'a stronger fabric.

Having now fully described my mvention, what I claim and desire to protect by Letters Patent is:

1. A knitted fabric composed of a numfirst chain. I

' 2. A knitted fabric composed of a num ber of longitudinally extending chains each of which'is composed of alternate series of loops, one pair of threads forming the loops of. one series and another pair of threads forming the loops of another series, the

loops of one series of one chain being interlocked with the loops of the adjacent series of thesame chain, and the pair of threads composing eachof said series of loops extending to, and forming a series of loops of,

another chain.

3. A knitted fabric composed of a number 'ofpairs of threads forming longitudinally extending chains, each of which is composed of knitted loops adjacent series of which are formed of two different pairs of threads, each pair of threads at the unction between adjacent series of loops of the same chain being interlocked with the other pair of threads and thence extending transversely to, interlocking with, and forming part of,

8. A knitted fabric composed of a numloer of longitudinally extending chains each of which is composed of alternating series of loops, each series of loops being composed of a locking thread and a locked thread, the said locking thread of one pair at the junction, between adjacent series of loops of the same chain, being looped around the locked thread of the pair of threads forming the adjacent series of loops and thence, together with its companion thread extending transversely and forming a series of loopsof another chain.
